Master Lock Company MLK3T High-security Padlock Pack of 2

Product Description

The MASTER LOCK COMPANY MLK3T is a high-security padlock sold in a pack of 2, built for demanding locking applications where cut, pick, and pry resistance are required. The body is constructed from laminated cadmium rustproof steel measuring 1-9/16 inches wide, giving it structural strength and corrosion resistance in harsh environments. A 4-pin cylinder provides pick resistance, while a hardened steel shackle with nickel plating resists cutting attempts. Dual locking levers engage the shackle on both sides to resist prying. Two brass keys are included per lock. This padlock is suited for facilities, job sites, storage units, and equipment yards where reliable physical security is a priority.

The MLK3T is designed for secure locking in commercial, industrial, and residential applications. Typical uses include securing gate hasps, storage lockers, tool cribs, trailers, and chain link fence access points. The laminated steel body construction makes it well-suited for semi-exposed outdoor environments. Each pack contains 2 padlocks, making it practical for multi-point security installations or replacement of worn hardware across a facility.

Installation Notes

Installation requires no specialized tools — the padlock is inserted through a hasp, chain link, or locking bar and closed by hand. Verify that the hasp or hardware gauge is compatible with the shackle diameter before installation. For outdoor or high-moisture environments, periodically inspect the shackle and body for wear and apply a lock lubricant to the cylinder as needed. Do not force the shackle if the cylinder does not turn freely.
